Coming from Bordeaux via the Deux Mers motorway, take exit 1 "Martillac - Saint-Médard d'Eyrans", then follow signs for "La Brède - Saint-Médard d'Eyrans", then "Saint-Médard d'Eyrans - Isle-Saint-Georges". Then, in the town, follow signs for "Cadaujac" (or "église") and cross the level crossing. The road goes around the church on the right: park in the gravel car park enclosed by log barriers.
(S/E) Take the Chemin de la Bugonne, which first runs alongside the multi-sports hall and its car park, then the water treatment plant, which you leave on your left.
After this, the track, which has been very passable up to this point, becomes semi-passable and runs alongside a forest, then meadows.
(1) Leave the track, which continues straight ahead along the (paved) Petit Brésil path. Turn right at a right angle onto the paved road. After 300-400 metres, just after the intersection with a road on your right, you will pass Château Turpaut. Further on, the road turns left at a right angle and passes under a power line. Continue to the village, which you will cross, and then follow the signs for "Ayguemorte - Bautiran".
(2) Opposite the church, cross the bridge and turn right along the Ruisseau de Saucats. At an iron cross, the road leaves the Saucats. At this iron cross, take the dirt path that runs along the right bank of the Saucats (on your left as you turn your back on the village). Follow this pleasant path along the stream until you soon reach the road and arrive at a footbridge.
(4) Cross this footbridge and you will now be on the left bank of the Saucats. Continue upstream towards the west, then south.
(5) You will arrive at the road between Ayguemorte-les-Graves (on your left) and Saint-Médard d'Eyrans (on your right). Those who enjoy beautiful religious buildings can make a detour to admire the beautiful church of Ayguemortes on the main street. Otherwise, turn right and continue for about 600 metres, where at certain times of day you may encounter some traffic.
(6) Leave this road by turning right onto a very quiet road that passes in front of the beautiful Château d'Eyrans (Chemin du Château). Take the opportunity to admire the beautiful traditional stone and wooden building on the left, opposite the vineyard, and the Château d'Eyrans a little further on the right.
(7) After the château, turn left onto Rue des Fauvettes, which gradually leads into the village and joins the station district.
(8) Turn left and cross the level crossing. If you're feeling curious, you can make a return trip to admire the beautiful old station building, which has been converted into a cultural centre. Otherwise, turn right towards the town centre.
(9) After passing a square adorned with a beautiful umbrella pine tree, turn right towards Cadaujac and continue towards the church that can be seen in the distance.
(S/E) Return to the car park opposite the church and the stadiums.
, mostly along the "Saucats" through fields. The section on the fairly busy road is really not very long, less than 500 metres. Very nice
